Honestly, before beginning this review we thought that ESA was going to turn out to be a pointless technology from Nvidia, that was nothing more than a cheap marketing ploy to try and sell more hardware. Although we did not embrace the technology right away, the more we began to play with it the more it all made sense. The ability to monitor and adjust virtually everything gives the user a great deal of control over their system and this is certainly something that enthusiasts will appreciate.
